Raw materials and manufacturing method 4.1 Raw materials The raw materials used for manufacturing waterproo
21、fing compounds shall be as follows: 4.1.1 Basic materials acrylic rubber, chloroprene rubber or rubber asphalt. The basic materials shall be urethane rubber ( l ) , Note (l) The case where the main agent and hardener react to become urethane rubber, or the case where the material of one compo- nent
22、type reacts with moisture in the air to become urethane rubber is included. For example, there are polyisocyanate or urethane prepolymer or mixture of both of them as the main agents and are combination of polyol and the like as hardener. 4.1.2 Mineral matter fillers carbon black, pulverized silica,
23、 etc. These shall be calcium carbonate, talc, clay, 4.1.3 Additives The additives shall be pigments, thickeners, crosslinking agents, antioxidants, surface-active agents, diluents, etc. 4.2 Manufacturing method The waterproofing compounds shall be manufac- tured by compounding the basic material, mi
24、neral mater fillers and additives, and by mixing and kneading uniformly. However, in the case of two component type waterproofing compound, it is manufactured by dividing the raw materials so that at the time of using the hardening begins by mixing. 5. Tests 5.1 General conditions of test test Diece

The The environment conditions for preparation of stanaard condition means the 20C ciass 2, 65 % class 20 20 f 2C (65 f 20) % of JIS Z 8703. The materials, container, mould frame and substrate plate shall be left as they are under t
26、he standard condition for not less than 24 h before test. (1) Sample For the sample, mix the waterproofing compound thoroughly by stirring to make uniform in quality, and as required, add diluent solution(2) of the amount specified by manufacturer, and further mix uniformly. However, as to the sampl
27、e for measuring of solid content, the diluent solution shall not be added. Further, in the case of two-component type waterproofing compound, weigh so correctly as to obtain the mixing ratio specified by the manufac- turer and mix uniformly to take it as the sample. Note (2) In the case where the ra
28、nge is specified for additive amount of diluent solution, it shall be the middle value of the range.
